Product Description

The Timbren FRF53A SES Rear Suspension Enhancement System is engineered specifically for 1989-2026 Ford F-53 motorhome chassis applications. This system utilizes Timbren's patented Aeon hollow rubber spring technology to eliminate rear suspension sag, reduce body roll, and improve handling when your motorhome is loaded. The progressive spring rate design means the rubber springs push back harder as load increases, automatically leveling your vehicle without any manual adjustments. Unlike air bag systems that require compressors, air lines, and constant pressure monitoring, the Timbren SES is completely maintenance-free after installation. The hollow rubber springs mount between the chassis and rear axle, working in conjunction with your existing leaf springs to provide superior load support with an 8,600 lb capacity per pair. Installation is straightforward and can be completed in approximately 30 minutes with basic hand tools--no drilling required for most applications. The all-weather Aeon rubber construction performs reliably in extreme temperatures from desert heat to freezing winter conditions, and unlike air springs, cannot be punctured or popped. Enjoy improved handling, reduced sway when passing semis or in crosswinds, and a comfortable ride whether loaded or unloaded. Backed by Timbren's Lifetime Limited Warranty and 100-Day Money Back Guarantee.
